Mechanical Testing of Metals

ASM HOMESTUDY COURSE (11 Lesson Series)

Course Overview:

This basic course will include lectures to define and discuss properties for which tests are made on fundamentals and applications of mechanical testing in metalworking industries, as well as laboratory demonstrations, including compilation and interpretation of data for practical applications.

It is intended for employees of industrial firms whose products or services require control and evaluation by mechanical testing. Those involved in such areas as product development, quality control, design and process engineering, production, supervision, sales and purchasing, will find it valuable.

The course will include "hands on" tensile testing and Rockwell hardness testing using automated equipment. The following companies have contributed equipment to the mechanical testing laboratory: United Testing Systems, LECO, Buehler, Wilson / Instron, Newage, Struers, Mitutoyo, King, Clark, and Krautkramer Branson.

Course Outline:

1. Introduction to Mechanical Testing: introduction to concepts; testing standards; testing system basics; data treatment and reporting; basic requirements for test facilities.

2. Instrumentation and Calibration of Mechanical Testing Equipment: calibration of universal testing machines; standardisation of test specimens; extensometers; hardness testing equipment; specifications and certification of calibration.

3. Hardness Testing: classification of hardness tests; macrohardness vs. microhardness; brinell test and equipment; rockwell test and equipment; miscellaneous hardness tests; special test requirements and concerns.

4. Fundamentals of Tension and Compression Testing: standards for tests; elastic/plastic behaviour; load/elongation curves; specimen design and preparation; data recording and interpretation.

5. Special Applications of Tension and Compression Testing: stress-strain curve--teachings and results; effects of specimen geometry, strain; rate, and grain size; true stress and strain; strain hardening (n coeff); anisotropy (r value); notch testing; stiff and soft tensile frames.

6. Shear, Torsion, Creep and Creep Rupture Testing: test procedures and fundamentals; equipment; specimen preparation; applications; data derivation and interpretation.

7. Ductility and Formability Testing: formability as a property; bend tests; sheet of formability tests; circle grid analysis; bulk-forming (upset) test.

8. Fracture Testing: ductile vs. brittle behaviour; impact tests, including Charpy V-Notch and Izod; dynamic tear; drop weight; fracture toughness tests.

9. Fatigue Testing Methods: fundamentals; equipment; stress-life data; axial vs. bending vs. torsion results; metallurgical variables in fatigue; low-cycle fatigue.

10. Computers in Mechanical Testing: introduction to computer technology; strengths and limitations of computer controls; data recording; repeatability of tests.

11. Circle Grid Analysis: the Forming Limit Diagram; shape analysis via the stretch-draw chart; distinguishing between tooling and design problems; making a material edge condition analysis; selecting the optimum lubricant by using coefficient of friction test data.
